SHOE TYING AND KNOTTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 329,519, dated November 3, 1885.

(No model.)

To all whom it may concern.-

Be it known that I, ALBERT WALTER \VEEKs, recently of Vorcester, now residing in Newton Upper Falls, county of Middlesex, State of Massachusetts, have invented new and important Improvements in Shoe Tying and Knotting Machines, of which the following is a full, clear, and concise description.

My inventions appertain to and are improvements upon the shoe-tying machine for which the United States of America granted a patent conjointly to Albert 1V. \Veeks, of \Vorcester, and Lawrence St. Clair, of Lynn, Massachusetts, said patent being numbered 274,236, and bearing date March 20, 1883.

The object of my improvements is to provide such devices and combination of devices as shall render the operation of tying shoes, or other articles which require to be attached the one to the other, more perfect and complete.

My invention consists in the combination, with a shoe tying andknotting machine, of a spring which so acts in conjunction with the hooks of the knotting device as to prevent the string from slipping off the said hooks while forming the knot.

It further consists in a new and automatic device for stopping the machine every time a knot has been formed.

a It further consists of an adjustable head to the standard receiving the shoe, whereby the distance from the inner sole of the shoe to the knot may be easily regulated.

, My invention further consists in the com bination, with a shoe-tying machine, of a device for cutting off the string every time two shoes have been unitedi. 6., at the end of every pair.

The improvements further consist in various details and parts and combination of parts, as will be hereinafter fully set forth and described.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

The following is a more detailed and'minute description of my improvements:

Descriptionof improvements to the'various parts of the lm0tter.The rotating and reciprocating sleeve E has the shoulder e and the splinekeye gprovided'to secure in position the smallercog-wheel M, the former to prevent it being driven-out of place {by the reciprocating and thelatter bythe rotating motion ofsaid sleeve,

- andth'us in either casedestroying the adjustment of the hooks e and f. This sleeveis further provided withthe hole e", through which the plunger F is lubricated, andalso with milled groove e for receiving and securing the hook-e. Attached'also to-this sleeve is the flattened pin E, for closing down the hook f. For-securing the accuracy of the motion of this sleeve'stillfurther, the wheels M and M have-been provided with solid cogs and a chain,I, hav-ing two long and thinand one short andthick links alternating, the short one adapted to fit between the cogs of said wheels'and the-longerones to span said cogs, as shownin Fig. 2'. Thetighten-ing-roller 19, consistingof-a frame having the slot 9 and carryingthe friction-roller 10 is provided to take up any slackness which may occurin the chai'n'I, being held many adjusted position by thescrewp -l-he flat spring G, having the pronged end G, adapted-to span the sleeve'E and rest against the wheel M, is provided to suddenly thro'wthe-saidsleeve and wheel in thejdirection-ofthe arrowuQ-and thusinsure the speedy transfer of the string from one hook tothe other, (represented in'Fig.;2 as

- just abou-t to take place.) For the more perfeet action of the knotter, the end'of the plunger F opposite that carrying the hook f is milledinto such'ashape as to fit the slotted end-'f of the lever F, which arrangement,

Fig. 21 is an end view of that Fig. 26

while allowing of reciprocal, effectually prevents rotary, motion. The same end of the said plungeris' further furnished with the screw f, which affords an easy method of adjusting and of attaching said plunger to the ing B. This nipple is further provided with the projection or lug h, the useof which,t0- gether with that of the hook f and the tapered end of the plunger F, and-their inutualrela' tions-will be more fully set forth-hereinafter. For the further accurate working of the knotter, a spring, D, has been secured to'the casting B by the screw a, and designed'to operate in connection with and to assist the hooks in forming the knot. spring is so shaped as to fit partially around the plunger F, and to just touch the top of the small hook fwhenthe latter stands at right angles with the plunger F in the position of spring and plunger shown in Fig; 1; At the same time the spring D allows'of plenty of room between itself and the plunger Fto allow of the free andeasy passage of thence dle P alongside of the plunger, as shown in Fig. 3. The spring D is further furnished with the lug d and the curved lip or corner (i the purposes of each to be set forth hereinafter. To adjust and'yet at the same time to limit the motion=of the spring D'inthe di rection of the arrow u,,the eccentric diskd is provided. By turning said disk around and securing it to the lug b by the screw 01 the springs motion in the said direction can be accurately adjusted. Under the knotter' and fastenedto-the main shaft Z by the set-screw n is the combined cam N andthe wheel M1 The wheel M is fittedupon theshoulderw, and provided with the slots M through which pass the' screws 72, by means of which it is firmly secured to the combinedcams' N. By loosening the screws-n and on account of the slots-M the wheelM can be turned around more or less upon the shoulder it, thus en abling the sleeve E andthelargehook eto be readily andaccurately adj usted'with relation to the cam edges n and a and throughthem to the plunger F and small hookf. The spiral cam edge a and the protuberance nupon' the cam edge a and their'relations to forming the knot will be more fully described hereinafter; The hanger O has upon its inner surface the projecting guides 0 0, between which the lower ends of the levers E andF' play,whichlevers are thus prevented from being bent or broken when acted upon by the'camedges a and n The hanger O has, further, the shouldered screw 0, which projects into a circular groove" The upper end of this the shaft Z.

, Description of the adjustablehead.Upon the top of the casting B is the adjustable head K,

which is secured to the perpendicular rods h and it. These rods are secured to the head K in a diagonal position, thus permitting the rod k to pass downward through and within the case B in front of the back end of the sleeve E, and the rod is to pass downward in a similar manner behind the front end of said sleeve, as shown in Fig. 1. This arrangement permits the free play of the knotter, and also of the springs G and D. The lower ends of said rods are secured to the casting h, having a square shank, which moves within the recess 1) of the lug B", and which is secured therein by the belt k across its surface,the said shank thus forming a guide to the lower ends of the rods and h. The casting k carries upon its lower end a loop,into which passes the end of the lever k which latter is pivoted in the split lug L ,cast upon the plate L. The opposite end of the lever h is flattened and forked to pass into the grooved edges ofthe square nut K into which screws the milled-headed thumb-screw K, which latter is prevented from moving up or down by a washer secured to it under the plate L. By turning the thumb-screw K either to the right or left, through the corresponding action of the lever h, the casting h", and the rods 7c and h, the head K is raised or lowered at will.

Description of the eutter.-Upon the small hub a of the arm a is secured by the screw 0 a knife, 0. The said knife 0 has a diagonal edge, and its lower end is of a forked shape, which latter, in connection with the screw 0 permits it to be readily adjusted or removed for sharpening. \Vithin a slotted lug, a, of the arm a is pivoted the pawl G, which is provided with the slit Oin one end, and at the same end has two depressions in its lower edge, one for receiving and keeping in position the end of the spring 0, and the other 1or receiving and retaining in position the stringl, when the latter is cut. At the slit end of the pawl O isa milled surface, Gflupon that side of the pawl which is nearest the standard or casting A, and upon thesame side of the knife, and adjustedto just touch the milled surface of the pawl when the latter is closed down over the knife, is the spring 0 About perpendicular under the knife and pawl, and secured to the shaft Z by the setscrew 0 the pinion e" is placed. Diagonally above this pinion, and secured to the lug L upon the plate L, by the shouldered screw 0 is the wheel 0*, which has upon its perimeter just twice as many cogs as has the pinion e, which drives it, thus giving to the wheel 0 but one revolution for every two revolutions of the pinion e. The wheel 0 has upon its face the projecting semicircular band provided at one end with the cam edge 0". Designed to come into contact with this cam edge and band, passing up through the plate L, is the rod e ,the upper end of which is slotted and pivoted to the pawl G at the opposite end from the slit 0.

The workings of these various parts of the cutter will be hereinafter more fully set forth.

Description of the string-distribnter.Pivoted upon the same arm,a, as carries the cutter is the string-distributer Y,having in its upper end the hole 3 through which the string from the ball contained in the cup J passes. The lower part of the distributer has the forked end Y, to which is attached by means of the shouldered screw f, the reciprocating rod Y". This rod is provided atone end with the spiral spring y", and it is still further provided with the pins y and y. These latter project past the edges of the lever B. as shown in Fig. 1, which lever,by coming into contact with them, gives a reciprocal motion to the rod Y which in its turn, gives motion to the string-distributer Y.

The following improvements relate to the presser-foot bar S, the lever B, and the cam Q, respectively: To prevent rotary motion, the presser-foot bar S has the groove S, into which projects the pin S As a guide to the lower end of the lever S which operates the presser-foot bar, is the slot or groove Z in the plate L. For strength, security, and to prevent friction, the leverR is pivoted to the lug A by means of the screw R, which has the shoulder R The upper part of the said lever has the forked end B, and is attached to the needle-bar P by means of the shouldered screw R". For the reduction of strain upon the lever R in converting the rotary motion of the shaft Z into reciprocal motion, the lower end of the said lever B has been lengthened and curved so as to come over upon the side of the cam Q. The friction-roller R is now placed at right angles to the lever B, and enters the cam-groove Q upon the side of the cam Q, as shown in Fig. l. The cam Q is secured to the shaft Z by means of the set screw Q. The cam-groove Q has been so modified as to permit the eye of the needle P to remain within the standard B until such a point in forming the knot as the large hook e has transferred the string P from itself to the small hook f, the object of this delay in withdrawing the needle P to be shown hereinafter.

Description of the stop-motion-Upon the main shaft Z, and operating between the hanger U and the wheel X, is the sliding sleeve W. The said sleeve has upon its back edge the lug w and upon its front edge the lug W. It further has upon its cylindrical surface the cam 10, the cam edge w, the square stop or lug w", and the band it. The said sleeve further has the slot W in which the pin Z plays, which pin is driven tightly into and through the shaft Z, thus permitting the sleeve W to have a free reciprocal motionupon the shaft, but preventing any rotarymotion, except as both sleeve and shaft turn together. The hangerU has upon that side which is nearest the sleeve W the recess U. Upon this same side, and directly under the sleeve, is the projection U, through which plays the slotted pin V. Projecting from the edge of this hanger is the arm U, to which is pivoted by means of the screw T the lever T. The upper part of the lever T passes up through the aperture Z* in the plate L, and the said lever has upon its lower part the arms T and T the latter arm adapted to enter the slotin the pin V, The arm T carries upon its surface the wedged-shaped lug or cam t* and the projecting pin or lug t. Just beneath the plate -L, and passing through the lever T, is the pin it, and working in connection with this pin is the lipped spring t, which is attached to the plate Lby means of the screw t. Working in connection with and forming a part of this stop-motion is the wheel X. The said wheel X runs loose upon the shaft Z, and is-held thereon and prevented from having any lateral motion by the screw acfiwhich projects into a circular groove in the shaft Z. The wheel X is further provided with the lug x,

the groove '00, for receiving the driving-belt,

and the aperture m, for admitting oil into the groove in shaft Z.

The operation of the stop-motion is as follows: The upper portion of the lever T is pressed toward the standard or casting A. In the first stages of its motion in this direction the pin Vis Withdrawn in a downward direc tion'from in front of the cam edge 10 and the square stop w upon the sleeve W. By

this time the thin edge of the cam-lug t has reached the lug 10 upon the back edge of the sleeve W. As the lever T is pressed still farther in the direction of the casting A, and under the influence of the cam-lug t and its contact with the lug w,the sleeve W is pressed toward the wheel X until their respective lugs :10 and W are interlocked. The rotary motion of the wheel X is now communicated to the sleeve WV, and by the pin Z to the shaft Z. By pressing forward the-lever T in the direction indicated the projecting pin or lug t has of course been lowered -in a like manner and proportion as the lug t. WVhen, therefore, the shaft and sleeve have made about a semirevolution, the cam-face wstrikes the projecting pin i and thus drives the lever T back again into its original position,while the band to", remaining in contact with the pin t prevents the lever from being again pressed in the direction of the casting A during that same revolution of the shaft. By this automatic motion of replacing the lever T the pin V has also been thrown upward into its original position. When, therefore, the shaft Z and sleeve W have nearly completed a revolution, the upper portion ofthe pin Vcomes into contact with the cam edgew, by which means the sleeve W is withdrawn from the wheel'X until the lugs m and W are disconnected. Just after this disconnection the pinV comes into contact with the square stop or lugw which stops the shaft every time after one exact revolution has been made.

To prevent a possibility of a disconnection of the lugs wand W during the revolution of the shaft Z, the lug 10 comes into contact with the-face U 'of the hanger U, and when the sleey e W is slid back under the influenceof the pin V and the cam edge to the said lug 20 passes into the beveled-lipped recess U in the said hanger.

As a guard against accidental starting of in front of the lip of the spring t,which spring then serves to keep the lever T inthis latter position until sufficient force is applied to overcome its resistance. The resistance last named is readily increased or decreased-by varying the strength of the spring-t.

For ease and efficiency in lubricating the pivots of the levers R,'E, and F,the oil-channels (1 and b are cast into the tops of the lugs A and B, respectively, and the apertures a and b have been provided in the backs of the respective castings A and B. Each of the castings A and B is provided with a cover similar to A to protect the inclosed mechanism. l

The opcrationof the machine is as follows: By pressing the lever T in the direction of the WVhen the lever T is replaced by the action of the cam w, the pin it is again brought casting A the machine is started,as above de scribed. Directly the shaft Z begins to rotate the presser-footis released and firmly pressed. against the work,and the needle-bar, under the influence of the lever B and cam Q, begins to move in the direction of the arrow u. At'the direction of the airow u the reciprocating rod- Y of the distributer Y is pressed in the same direction by the action of the spring y,thus at once giving a slackness of the string B". By

.the time the needle-bar has reached the limit of its motion in the direction of the arrow u, having forced the needle and string through the work and passed into the standard B, by this time the plunger F has reached its limit in the inverse direction and the lip f of the hookf has been pressed tightly against and projects slightly over the lug h of the nipple-H, in the manner shown in Fig- 6. This makes the closing down of the hook f impossible while it retains this position. The spring D now just touches the top of the hook f,with its lug d just touching and extending back of the projecting head f of the hook f, as shown in Figs. 1 and 3. During the motion of the me die-bar and plunger above described the sleeve E,by simple rotary motion,has been bringing around the hook 6 into a position very near the hook f. The needle-bar, actuated by its lever and cam,now makes a slight suddenmotion in the inverse direction of the arrow it, thus forming a loop in the string P just back of the small hookf. Owing to the pinsy and 3/ on the distributer-rod Y being placed somewhat farther apart than the width of the lever I R, this slight inverse motion of the said lever does not affect the distributer Y. The large hook e, by its simple rotary motion, passes into the. above-said loop and past the back of the hookf in such a way that the end of the hook 6 just touches the back of the hookf. At the exact time that the large hook c has passed the back of the hook f the abrupt part a of the cam edge n has been brought against the lower part of the lever E Actuated by the lever and cam edge, the large hook e is driven suddenly and closely past the back side of the small hook f, as shown in Fig. 1. As the lugd upon the spring D projects back of the hook f, as before stated, and in such a manner as to permit the hook e to just go beneath it, as shown in Fig. 3, when the hook e is pushed past the back side of the hook f, as described, the lug d presses the loop of the string P onto the hook e, as shown in Fig. 1. As the sleeve E continues to rotate in a spiral course inversely to the direction of the arrow u, and governed by the cam edge a the flattened pin E passes the back of the hook f without touching, and the string P is drawn through the eye of the needle P behind the hook f, which latter is being firmly held in an erect position by the lug h. \Vhen the hook e in its spiral course has made about half alrevolution since entering the loop, it strikes the lip (1 of the spring D; and as the hook 6 continues its course the spring D is pressed in the inverse direction of the arrow, while the end of the hook e traverses the path of the dotted line shown in Fig. 3. The motion of the hook e continues until it again comes under the lug d, and passes in front of and just past the point of the small hook f, as shown in Fig. 2. During this latter motion of the hook e the needle has been slightly more withdrawn in an inverse direction of the arrow u, but the eye of the needle is still within the casting B, as is also shown in Fig. 2. By thus, through the agency of the cam-groove Q, and lever B, permitting the eye of the needle to remain as near as possible to the back of the hook f while the large hook e is drawing a supply of string therefrom the minimum of friction and strain is caused to the hook f and the string 1?. When the hook c has reached the position shown in Fig. 2, one strand of the string is above and the other below the point of the hook f. Exactly at the moment hook c has reached this position the lower end of the lever E drops off from the end of the cam edge a, and under the influence of the spring G the sleeve E and hook e are snapped back in the direction of the arrow at. The lower strand of the string I going under the hook f, and thetop strand coming up against the projected head f of the said hook, the loop is completely transferred from the large hook e to the small hook f. At the same time that the hook e snaps back the spring D follows it up and assumes its former position, thus pushing the string 1? on and upon the small hookf, and holding the string firmly thereon between itself and the projected head f of the said hookf. This action of thespring D renders the transfer more sure, and at the same time prevents the loop from rebounding off from the small hook f. Under theinflucnce of the cam-groove Q and the lever B the needle-bar P and the needle P are now rapidly withdrawn in the inverse direction of the arrow at. The lever B, striking the pin 1 in the distributer-bar Y gives motion to the distributer Y, which thus gathers string for the next knot. Just as the above motion of the needle-bar begins the lower end'of the lever F drops into the recess upon the cam edge a and under the influence of the spring pressing the lower end of this lever the plunger F is suddenly snapped in the direction of the arrow to. Just as the plunger F is thrown back the flattened pin E is directly behind the small hook f, and closes said hook down as the plunger falls back. Owing, now, to the inverse motion of the needle-bar, the action of the distributer, the closing down of the small hookf, and thetapering shape of the end of the plunger F as the latter falls back,the stringis withdrawn from behind the small hook f and the knot formed and tightened, as shown in Fig. 5. As the sleeve E is rotated still more the flattened pin E passes off from upon the head of the hook f, thereby permitting said hook to assume its erect position. At the same time the lower end of thelever F is brought into contact with the protuberance n upon the cam edge n, whereby the plunger F is again slightly ad vanced in the inverse direction of the arrow at. Any tightness of the string or loop around the hook f is thus slackened and the loop of the completed knot thrown off from the hook f. As soon as the needle bar P, in the inverse motion above described, had withdrawn the point of the needle 1? to such an extent as to permit the pawl O of the cutter to pass it, exactly at that moment did the lower end of the rod 0 come into contact with the cam edge 0 upon the wheel 0 By the action of this cam edge and the'rod c the pawl O is lowered directly across the string (which stretches in a line from the needles eye to the point where the needle entered standard B) in such a way that the said string is held in the indenture which is upon the lower edge and about midway the length of the slitG in the pawlLG. As the said pawl is pressed still farther down the diagonal edge of the knife '0 passes up through the slit in the pawl 0, thus severing the string. The shortaend of the string 1, which reaches from the needles eye to theiknife, is now held firmly against the milled surface 0 of the pawl O by the spring 0 thus preventing the short end from slipping out or being pulled through the eye of the needle. During this operation of the cutter the presser-foot has been withdrawn from the work. At this point, under theinfluence of the stop-motion, the machine stops, leaving the lower end of the rod 0 ,of the cutter upon the highest point of the cam edge e onthe wheel 0 and the pawl 0 closed down, as shown in Fig. 13. Upon again starting the machine for the formation of another knot, the needle-bar and needle 1 and 12,) the pawl 0 being kept down, and

the short end of the string thus held-firmly by the influence of the band 0", which keeps the rod 0 raised to its highest point. When, at the completion of this second knot, the point of the needle P is again withdrawn in the inverse direction of the arrow u to such an extent that its point clears the pawl C, at that moment, by the rotation of the wheel 0 the endof the band 0 passes from under thelower end of the rod 0 The pawl 0, under the influence of the spring 0, is now raised, the short end of the string is released,and the cutter is again in the position shown in Fig. 1, and ready to again sever the string at the completion of the next-i. 6.,13116 thirdknot, and so on alternately.

It will be seen and understood that the knotting-machine inv all its essential parts is applicable for many purposes besides that of tying up shoese. g., rubbers, hose, gloves, or any other articles which need to be united in pairs, or by putting two knots into one article to form a loop for suspending the same, or for the further purpose of putting strings into tags, bills, or pamph-lets,or, in fact, anything which may need to have a string passed through it with a knot formed at one or at both ends.
